Lady Murasaki and Marital Strife

Lady Murasaki, one of the most famous women of Heian-period Japan, and the first novelist in Japan, wrote many wonderful romantic scenes through the Tales of Genji, yet her real life marriage was anything but.

The latest episode historical drama on NHK about the life and times of Lady Murasaki (poem 57, め) covers her marriage to her second-cousin Fujiwara no Nobutaka (藤原宣孝, ? – 1001), who was around 20 years her senior. Yes, this was not that unusual for the time, but still gross.

Sadly, the marriage quickly turned sour. Nobutaka slept around a lot, and had other hidden wives and children. Lady Murasaki did not take this lying down and the two of them fought frequently. Nobutaka for his part, enjoyed bragging about his trophy wife.

In the poems preserved in Lady Murasaki’s own private collection is this poem addressed to her husband:

JapaneseRomanizationRough Translation1
言ひ絶えばIi taebaIf you saw you’re going to
さこそは絶えめSa koso wa taemestop writing me, then fine!
なにかそのNanika sonoYou can’t even
みはわらの池をMiwara no ike wostand by the bank
つつみしもせむんTsutsumi shimo senof Miwara pond properly.
1 Apologies for any mistakes, or for the roughness of this translation

The backstory of this poem is that Nobutaka had taken one of Lady’s Murasaki’s private letters addressed to him, and shown off that letter to friends (apparently bragging about how smart his young bride was). She was justifiably angry and told him to knock it off. Nobutaka was angry with her and threatened to stop writing. Her reply above, was a clever way of saying “fine, don’t bother writing me”. The allusion to Miwara pond was a pair of puns:

  • Miwana pond (mihara) is also a pun for anger.
  • The word tsutsumi is also pun for a bank (as in riverbank), and self-restraint.

Contrary to Lady Murasaki’s reply, Nobutaka was so impressed by the reply that he ended up bragging about it to his friends anyway. 🤦🏼‍♂️

Another letter is as follows:

忘るるはWasururu waForgetting others is
うき世のつねとUki yo no tsune toa part of this ephemeral world,
思ふにもOmou ni moEven so,
身をやるかたのMi wo yarukata nobeing forgotten myself,
なきぞわびぬるNaki zo wabinuruI cannot help but cry.
2 Apologies for any mistakes, or for the roughness of this translation

The married nobility of the Heian Period frequently lived in separate estates, and the husband would visit his wife as needed, but not the other way around. It seems by this point, Lady Murasaki was forgotten by her philandering husband, and lamented her unhappy marriage. One can’t help but recall the Gossamer Years generations earlier.

It is sad that such a talented woman was relegated to an unhappy marriage with a faithless, not to mention narcissistic husband, especially in a society where women had little recourse. I also wonder how much this motivated her to write her novel, The Tales of Genji, as a coping mechanism.

Love Triange, Part Two: Manyoshu Book One, Poem 21

A while back I wrote about a famous poem in the Manyoshu anthology by Princess Nukata addressed to her ex-husband Prince Oama (later Emperor Tenmu). It seems that the story of this forbidden encounter in a field of grass did not end there, because Prince Oama replied back…

1 Apologies for any mistakes in this translation. This poem was particularly difficult for me.

Before we discuss the poet and the context, I wanted to briefly explain the plant described: murasaki (紫草). I had some trouble finding information on this plant, but it seems to be the species Lithospermum erythrorhizon which in English has a variety of names: purple gromwell, red stoneroot, red gromwell, etc.

Princess Nukata was Prince Oama’s ex-wife, but had remarried his older brother, Emperor Tenji (poem 1 in the Hyakunin Isshu), while the emperor had compelled Prince Oama to marry his own niece (Tenji’s daughter) Princess Unononosasara to strengthen the family line. Relations in the family were complicated. Later after Emperor Tenji died, Prince Oama went to war against Tenji’s son, and overthrew him to become Emperor Tenmu. Game of Thrones, Japanese ediiton.

Yet what makes this exchange of poems surprising is that both Princess Nukata’s poem, and Prince Oama’s were recited not in secret, but at a big public banquet in front of Emperor Tenji.

So, what’s going on here? Are they professing their love in defiance of the Emperor?

Well … no. My book on the Manyoshu strongly suggests that given the circumstances these poems were likely recited in jest. Maybe they did still have lingering feelings for one another, but the poems were not meant to reflect real life; they were meant to paint a beautiful, but surreal scene. The imagery is fantastic, and a testament to their poetic skills, but the scene described likely did not happen. This is not unusual with the poetry we’ve seen thus far on the blog: many poems paint idealistic scenes that might be based on real life, but didn’t necessarily happen.

Then again…. what if they recited their poems in jest in order to hide true feelings after all?

One can’t help but wonder…. 🤔

Feeling Young, Kokinshu Poem 52

While re-reading the Pillow Book lately, one of the people in Sei Shonagon’s anecdotes recites a poem from an Imperial anthology: the Kokin Wakashu (Kokinshu for short).1 When I looked up the poem, it really struck me when I read it. Since I have an English translation of the Kokin Wakashu, and since many of the poems from the Hyakunin Isshu were originally published in the Kokin Wakashu, I figured it would be fun to post other poems from the same anthology.

This poem, poem number 52 of the Kokin Wakashu, reads as follows:

JapaneseRomanizationTranslation
年ふればToshi furebaAs the years stream by
よはわひいはわ老いぬYowai wa oinumy own life passes from me
しかはあれどShika wa aredostill I am renewed
花をおし見ればHana oshi mirebawhen I but see the blossoms
物思もなしMono omoi mo nashimy heart’s sorrows disappear
Translation by Laurel Rasplica Rodd and Mary Catherine Henkenius

The headline of this poem reads “seeing cherry blossoms in a vase before the Somedono Consort [Empress]“.2

The author of the poem, Fujiwara no Yoshifusa (藤原良房, 804 – 872), was the first member of the Fujiwara clan to assume the post of Regent to the emperor. This was at a time when the Fujiwara were a rising star in the Imperial court, had married into the Imperial family, and Yoshifusa was the grandfather of the young Emperor Seiwa. So, he had much to celebrate. However, even the powerful grow old and die, and Yoshifusa was no exception.

What I really like about this poem is that in spite of his own fears of growing old, he still can enjoy life here and now and feel young again.

I am at the age where I can definitely start to feel my age, and the years ahead of me are likely fewer than the years behind me, and yet I am rarely bothered by it. I often find moments of joy in life, playing with my kids, enjoying nerdy fandom, and savoring poetry like this, so I know how Yoshifusa feels.

1 Nowadays, people quote movies, TV shows and such. I can quote more gags from The Simpsons than I care to admit. Back then, people quoted poetry from earlier generations.

2 Many poems in the Kokin Wakashu included a headline to explain the scene of the poem, or provide some background. These were not carried over when the poems were collected in the Hyakunin Isshu since they were already well-known poems, or possibly just for the sake of brevity.

Omi Shrine

One of most iconic places in the world of Karuta is a placed called Omi Shrine, also called Omi Jingu (近江神宮, おうみじんぐう) in Japanese. It is here that the big championship events are often held, and it is a big part of season one of the anime series Chihayafuru. Not to sound like a cliché, but it is a kind of mecca for the Karuta world and the Hyakunin Isshu.

A scene from Chihayafuru as Chihaya approaches the Rōmon gate.

What is Omi Shrine though?

You see, Japan has essentially two religions that co-exist: the native Shinto religion and imported Buddhist one. We don’t need to go into detail about how they differ; I have an entire blog on the subject. Suffice to say, they differ. Even the place names are different. Buddhist temples are called otera or end with -ji. Shinto shrines are called jinja, jingu or taisha.

Anyhow, Omi is a Shinto shrine located in the city of Ōtsu, in Shiga Prefecture. This area was once the province of Omi, hence the name. The shrine’s constructed began in 1937 and finished by 1940. It is a young shrine, but has a deep connection to the past.

Like all Shinto shrines, Omi Shrine venerates a kami, a divine figure. A kami can be a god (think ancient Greek gods) from Japanese mythology, a local spirit, or even a historical figure. Some shrines venerate more than one kami.

Omi Shrine venerates none other than Emperor Tenji, who wrote poem one of the Hyakunin Isshu (あきの). During his reign, the capitol of Japan was moved to Otsu city and there he reigned until his death. Here, he carried out many essential reforms that provided the foundation for Japanese society for centuries. Because Tenji also wrote the opening poem of the Hyakunin Isshu, the shrine became quickly associated with the anthology and with Karuta.

The shrine website even has a handy catalog of the Hyakunin Isshu poems, not unlike mine. 😉

The English website is pretty limited, but the Japanese site has a lot of great information about the shrine, Karuta and so on.

The shrine is a bit removed from the usual touristy areas, so you might not be able to get there. However if you do go, it’s good etiquette to pay respects to the kami there. Per Shinto tradition (explained here) the process is:

  1. Bow deeply at the waist twice.
  2. In reverence, clap twice.
  3. Bow once more.

You can also use the water font nearby to wash your hands a bit (just watch how other Japanese do it) and your face a bit before facing the kami.

You can also pick up an omamori charm too.

I haven’t been to Omi Shrine myself but it seems like a lovely, scenic location, and I would love to play Karuta there someday even if I get crushed.

The Pillow Book

Since I spent so much time gushing over First Summer Uika and her portrayal of Sei Shonagon in the Japanese drama Hikaru Kimi É (“Addressed To You, My Radiant One”), this seemed like a good time to talk about the Pillow Book, or Makura no Sōshi (枕草子).

Despite the name “Pillow Book”, the book has no erotic content. Instead, it is a collection of witty musings about life in the Heian Period aristocracy, early 11th century. The image is of a person lying on their pillow, composing thoughts in a diary.

The author, Sei Shonagan (poem 62), was one of the pre-eminent writers of her generation, in a field of many excellent talented women.

I had read the book many years ago, and I felt it was a bit dry at times since it has no narrative. But back then, I also had a much more limited understanding of Heian Period culture, and many of the things mentioned in the Pillow Book are also alluded to in the Hyakunin Isshu, as well as the Diary of Lady Murasaki. So, even if the format is different, all three collections draw from the same “cultural well”.

I thought I had lost my copy of the Pillow Book (the Penguin Classics version, translated by Dr Meredith McKinney) a long time ago, but was amazed to discover that it was just buried behind other books. So, I dusted off the book and have been reading through it again.

Sei Shonagon is a keen observer of life in the Heian Period, and makes lists for all kinds of obscure things:

[23] Occasions that induce half-heartedness — The religious services on days of Buddhist fasting. Preparations for something still far in the future. Long periods of seclusion at a temple.

trans. by Dr Meredith McKinney

or:

[65] Poetic anthologies — The Manyōshū. The Kokinshū.

[66] Topics of poetry — The capital. The kudzu vine. The water burr. Horses. Hail.

trans. by Dr Meredith McKinney

Or she adds things to lists that were probably drawn from personal experience:

[132] Occasions when time drags by — An abstinence that you must observe away from home. A game of sugoroku when you can’t manage to get your pieces off the board. The house of someone who’s failed to get a promotion in the Appointments List. And of course the worst of all is simply a day of heavy rain.

trans. by Dr Meredith McKinney

It’s also clear that Sei Shonagon had a pretty haughty attitude, especially when compared to Lady Murasaki’s (poem 57) withdrawn, melancholy tone or Lady Izumi’s (poem 56) whimsical passion. As they say in modern Japanese: seikaku ga deru (性格が出る, “people’s personalities come out”). In one anecdote, section 94, she grumbles about encountering “worthless peasants”. I wouldn’t be surprised if she was the only one among the nobility at the time who held such views, but it is nonetheless painful to read.

One thing I do particularly enjoy about the Pillow Book though are the anecdotes. While many of the entries are just lists and her opinions, she often reminisces about funny, sad or strange occurrences she witnessed during her 10-year tenure serving the ill-fated Empress Teishi. Some of these anecdotes and observations are quite long, while others are brief. Some happened long ago, and Sei Shonagon’s memory is a bit fuzzy, others are more recent.

For example in one anecdote, number 79, she talks about how her relationship with one Officer of the Left Gate Watch named Norimitsu had soured after an incident where he covered for her. She had gone somewhere and only Norimitsu knew her whereabouts, but the Captain Consultant demanded to know where she had gone and Norimitsu tried to keep his mouth shut. Later when Norimitsu complained, she sent a piece of dried seaweed in reply, and Norimitsu got annoyed. She criticized his lack of sense, and he was frustrated at her for putting him in such a difficult position. Later she muses that they grew more and more distant after that incident until “later, Norimitsu was promoted to Deputy Governor of Tōtōmi Province, and the relationship ended in hostility.”

Sei Shonagon discusses many people of the Court, including other ladies in waiting, but does not mention Lady Murasaki and other famous women of the Hyakunin Isshu. Such women served under the second empress, Shoshi, and thus came a bit later anyway. By the time Emperor Ichijo married a second time, Teishi’s status had greatly declined and her retinue (including Sei Shonagon) were on their way out the door. Teishi herself soon died in childbirth.

The Pillow Book is a really nice “slice of life” look at the court culture of the time: sometimes amusing, sometimes exquisite, and sometimes depressing. Her wit really shows through the ages and even today kids in Japan (and people outside Japan) still read her book.

Teika’s Handwriting!

In other recent, exciting news, I found this article on the Asahi Shimbun newspaper: the discovery of some of Fujiwara no Teika’s personal notes. This is called the kenchū mikkan (顕注密勘).

Long before Fujiwara no Teika (poem 97) compiled the Hyakunin Isshu, he served as a minister under Emperor Gotoba (poem 99). Among his duties, Teika was commissioned in 1201 to compile a new Imperial poetry anthology, which later became the Shin Kokin Wakashu (新古今和歌集).

Here you can see some of his notes and thought process as he’s compiling the poems together. It’s a fascinating discovery.

You can click here to see more detailed photos of his notes. They are read from right to left, vertically not horizontally.

You can also see another example of his handwriting here, courtesy of Wikipedia, from diary:

Teika himself had a pretty rocky career and after his liege lord was exiled, Teika spent the rest of his days living as a Buddhist monk. Nonetheless, his legacy lives on.

Lady Murasaki Drama

Hi folks!

I have been away for a while due to various life circumstances, but I’ve been wanting to share this news with readers.

The Japanese public TV station, NHK, broadcasts a new Taiga Drama (大河ドラマ) every year. These are big productions featuring some aspect of Japanese history, with big name actors and so on. I was very fond of the last one. Usually these cover periods of warfare or conflict, and male historical figures from Japan’s long history, but this year’s drama, titled Hikaru Kimi E (ひかる君へ, “Addressed to You [my dear Radiant One]”), features Lady Murasaki as the main character!

(Image by NHK, all rights reserved)

Lady Murasaki, poem 57 of the Hyakunin Isshu, needs little introduction. She composed the Tales of Genji, as well as her eponymous diary. She was the first female novelist in Japanese history, and has been a subject of interest ever since. The biographical details of her life are somewhat scant, unfortunately, and the drama does embellish quite a bit, including hinting strongly at a romance that probably didn’t happen in real life. My impression is that they are using romantic themes from her novel, the Tales of Genji, as the backdrop for the drama.

Nonetheless, I have been watching this series on Japanese TV1 and I enjoy it. It is somewhat different than past Taiga Drama, since it features a female main character, and this period of history (the late Heian Period), had little warfare, but it does have tons of scandal and intrigue as the Fujiwara clan tighten their grip on the reins of government. This drama is surprisingly risqué in parts, something you usually don’t see in a conservative Japanese drama. However, such scenes remind me more a more subdued Victorian romance than something in modern, American television.

That said, it’s a darn good drama thus far.

The drama frequently shows other people of the Heian period aristrocracy, many of whom were poets of the Hyakunin Isshu. To name a few who have been featured in the drama:

I admit I am particularly fond of the character Sei Shonagon. In historical pop culture, Sei Shonagon and Lady Murasaki are treated as rivals as they were both famous writers of the same generation who belong to rival cliques in the aristocracy, but in reality they probably didn’t interact much. Nonetheless, they frequently talk in the drama, and the actress who plays Sei Shonagon, stage name is “First Summer Uika” (ファーストサマーウイカ), is a talented actress and total babe:

She is on Instragram, too:

First Summer Uika also recently visited a Shinto shrine devoted to Sei Shonagon in Kyoto called Kurumazaki Jinja (車折神社), which even sells Sei Shonagon charms (omamori):2

But I digress.

Because the drama features so many people related to the Hyakunin Isshu, the drama subtly works in many poems from the anthology. It’s been great to suddenly recognize a poem being recited, even if I am a bit slow to recall. The settings, costumes, and cast are all amazing, and even though the historicity is questionable, it’s been a great watch.

I really hope they eventually make an English subtitle version so people outside Japan can watch. The quality of Taiga Dramas are terrific, and they are well worth watching if you can.

Update: while visiting Kyoto in 2024, we found a local NHK display of the drama:

The second photo above is First Summer Uika as Sei Shonagon.

1 Sadly there are not foreign translations, and no subtitles, and it is not always modern Japanese, so I admit I struggle at times to follow the story. At other times, I can follow easily enough.

2 We are going to visit Japan again this year (the last for our teenage daughter), including Kyoto. Visiting this shrine is definitely on the itinerary, even thought it’s pretty small.

Names in the Hyakunin Isshu

Hello readers,

If you’ve been following this blog for a while, and gotten to know some of the authors of the Hyakunin Isshu, then you may have noticed some patterns with the names of the authors. The authors are rarely listed by their birth name, and instead are listed under a sobriquet, or just their official title in the Imperial Court.

Why was this done?

My book, the Hyakunin Isshu Daijiten, explains that this was because in this period of Japanese history, names were thought to be tied to one’s life. People at this time, both the Nara (8th c.) and increasingly in the Heian (9th – 12th c) periods, were often worried about curses, evil spirits, and such, and went to elaborate lengths to avoid spiritual calamities (see background for poem 24 for example). So, to avoid risk of one’s name (and thus one’s life) being subject to evil magic, people often hesitated to share their personal names with others.

It’s unclear how commoners in the Nara/Heian Period named themselves; there is just not enough information, but for the nobility who all belong to the hierarchical Imperial Court, certain naming conventions developed.

Men

Men with important titles, or positions in the court often used their titles as their sobriquet. Lower-ranking men in the Hyakunin Isshu did not have this privilege.

  • Titles for members of the Imperial Family – Emperor Tenji, (poem 1), Retired Emperor Go-toba (poem 99), and Prince Motoyoshi (poem 20).
  • Positions in the Imperial Court – Sanjō Minister of the Right (poem 25), Major Counselor Fujiwara no Kintō (poem 55), and Master of the Grand Empress’s Palace (poem 83)
  • Clerical names – Dharma Master Jakuren (poem 87) and Former Major Archbishop Gyōson (poem 66)
  • Poetic names – Sarumaru Dayū (poem 5)

Women

Due to the Confucian, paternalistic culture of the Japan in antiquity, women were not given titles wihtin the Imperial Court (though they did earn rank just as men did), and seldom used their real name. Instead, they used a different naming convention.

  • Male relatives or spouses – Lady Ise (poem 19), whose husband served as governor of Ise Province, Lady Izumi (poem 56) whose tenure as governor of Izumi Province, “The Mother of Michitsuna, Major Captain of the Right” (poem 53), Taiyu of the Household of Princess Ryōshi (poem 90), and Ukon (poem 38) named after her father’s position as Captain of the Guards.
  • Poetic sobriquets – Lady Murasaki (poem 57) named after a character from her own novel the Tales of Genji, Akazome Emon (poem 58).

Because women were more often kept out of sight than men in the Imperial Court, biographical information about women authors of the Hyakunin Isshu is often much thinner than the men (except lower-ranking men). This makes learning about women like Lady Murasaki or Lady Izumi difficult.

In any case, the idea that names are tied to one’s lifespan is a fascinating cultural belief, and it’s likely you would find this in other pre-modern cultures as well.

Interview with Karuta Peru Club: History of the Hyakunin Isshu

Hello readers,

Recently I mentioned an upcoming interview with the Karuta Peru Club via Steph, a fellow karuta player.

I am happy to report that we finished our interview and it is available on YouTube!

Also available on Spotify in podcast form:

In this episode, Steph and I mostly discuss the history of the blog, but then talk about some of my favorite historical figures in the Hyakunin Isshu, such as Sugawara no Michigan’s (poem 24) and Lady Izumi (poem 56), among other things. It was a fun conversation and Steph was a terrific host.

I do sometimes use the word “um” a lot, especially when I am a bit nervous (this was my first interview), but I hope viewers and listeners learn something new, and enjoy the conversation too!

In the next episode, we plan to focus more on our experiences playing kyōgi Karuta (competitive karuta). Stay tuned!

Big thanks to Steph for making all this happen. 🎉

1 Manyogana and pronunciation source

Due to length and complexity of poem, plus it’s very old Japanese, I can only offer a rough translation (based on modern Japanese ones) like so:

A basket. The beauty holding the basket. A digging tool (lit. a spatula-like tool). The beauty holding the digging tool. You who are on the hill gathering vegetables, tell me, what family do you come from? Do you not know? I am the sovereign of this land (lit. Yamato, old name for Japan), and that every corner is under my dominion? So, tell me, what is your family’s name and origin?

This poem was composed by Emperor Yūryaku, who reigned in the 5th century, before recorded history. Technically, the title of “Emperor” was not used by ancestors of the Japanese imperial family at this time, and was later implemented by the time of Emperor Tenmu, brother of Tenji (poem 1), but this is a retroactive title. At this time, Yūryaku and others of the lineage were more like great kings (daiō 大王). Interestingly, although this point in Japanese history is pretty murky, Yūryaku is mentioned on a dedication inscribed on an ancient sword, providing historical evidence that he did in fact exist.

Yūryaku was described in early historical documents as a strong ruler, who slew his brothers following the death of the last king/emperor to get to his position. In later years, he helped consolidate power, but also was described as tyrannical as well.

The poor girl whom the poem was addressed to probably wasn’t in any position to say “no”, in any case.

The reason why I posted this poem is two-fold.

First, this poem is noticeably different than the tanka (短歌, “short poem”) style poems of the Hyakunin Isshu. This is a chōka (長歌, “long poem”) style poem. Tanka poems, including all poems of the Hyakunin Isshu, follow the style of 5-7-5-7-7 syllables. Chōka poems were 5-7-5-7-5-7…..5-7-7 syllables, with as many 5-7 syllable verses as needed. The Manyoshu has both formats, but by the time of the Hyakunin Isshu, the chōka format had fallen out of favor, probably because it was simply too long and difficult to fire off verses quickly.

Yūryaku’s poem doesn’t fit the chōka format very closely though, so it’s hard to say how strict poetry was back then. Over the centuries, and by the time we get towards the end of the Hyakunin Isshu, the style poetry had definitely solidified into a very rigid format with many specific rules, customs, and phrases. Yūryaku’s poem reflects an earlier, looser style of poetry. Or, as a powerful sovereign, maybe he just didn’t care. Who’s to say?

Second, the tone of the poem (ignoring the power-imbalance between him and the girl1) is a very lighthearted and romantic tone. Early poems in the Hyakunin Isshu tended to have a similar tone, but gradually the tone tended to get more somber centuries later as the aristocratic culture came to an end. Compare poems 95-100 to poem 1-5 in the Hyakunin Ishsu, and you’ll see what I mean. Yūryaku’s poem definitely belongs to this earlier, more bucolic time.

Anyhow, it’s interesting how poetry reflects history as well.

1 When you look at Lady Murasaki’s diary as well, when Michinaga makes a pass at one of the servant girls, it’s strongly implied a visit later will certainly follow. Again, women back then had less agency, and would have been hard-put to say no to powerful, ambitious men like that.
